So Cassandra Clare has just announced that Barnes and Noble has agreed to make a Special Edition of her new book City of Fallen Angels. This new book is the fourth book in the Mortal Instruments Series. She has also said that she might come out with a short story that connects the time gap between City of Glass and City of Fallen Angels. She said this in her live journal which can be found here: http://cassandraclare.livejournal.com/50679.html
